Analysis of mineral oils (MOSH/ MOAH)

Mineral oil hydrocarbons (MOH) can enter food commodities and processed products anywhere along the food processing and trade chain. At Eurofins Food & Feed Testing, we support you to ensure that your products are free from harmful levels of MOH, especially toxicologically relevant 3-7 ring MOAH, so you can meet regulatory requirements and maintain consumer trust.

Key services

  • Quantitative analysis of MOSH and MOAH using online-LC-GC-FID (high laboratory capacity available)
  • Mass spectrometric characterisation of MOSH and MOAH fractions using two-dimensional GCxGC-ToF-MS to elucidate the origin of the contamination
  • Quantification of the tri- to polyaromatic fraction (TPAF) of MOAH using GCxGC-FID as a basis for toxicological assessment recommended by EU for confirmation of positive MOAH
  • Characterisation of MOSH and MOAH profiles to distinguish between technical and naturally occurring hydrocarbons
  • Screening of raw materials, intermediate and final products, including all relevant raw materials and processed food
  • Verification of contamination sources, including migration from packaging or environmental exposure
  • Support with product recalls and crisis management, including rapid turnaround and expert interpretation
  • Customised reporting and regulatory guidance for national and international markets

Additional services

Beyond standard testing, Eurofins Food & Feed Testing also offers:

  • Consulting on mitigation strategies, including packaging optimisation and supplier audits
  • Trend monitoring and batch comparison for quality assurance and long-term safety evaluations
  • Continuous development of analytical portfolio, ensuring our methods remain at the forefront of scientific and legislative standards
